Fat Man (bomb design)

Fat Man was a nuclear bomb design used during World War II, notable for being the second atomic bomb dropped on Japan, on Nagasaki. It employed a plutonium core and a technique called "implosion," where conventional explosives compress the plutonium into a supercritical mass, resulting in a nuclear chain reaction. The bomb's unique, bulbous shape led to its nickname "Fat Man." Designed to maximize destruction, Fat Man caused immense damage and loss of life, ultimately playing a role in the conclusion of the war. Its development marked a significant moment in military history and scientific advancement.
